摘要： A video tape recorder which records video signals on a magnetic tape in such a manner that a first signal having luminance information and a second signal having chrominance information are recorded alternately on each track and the first signal recorded on each track is adjacent to the first signal recorded on an adjacent track and the second signal recorded on each track is adjacent to the second signal recorded on the adjacent track. The first signal and the second signal are exchanged every predetermined period L to obtain two combined signals each composed of the first and second signals which occur alternately at intervals of the predetermined period L.

摘要： A magnetic tape recording/reproducing apparatus for recording video signals on a magnetic tape without providing a guard band between each two adjacent signal tracks. The apparatus comprises a first switching circuit for exchanging 2-channel component signals every nH period to obtain two combined signals each composed of the 2-channel signals which alternate every nH period, two modulators for modulating the two combined signals, a head section having two pairs of rotarty magnetic heads for recording the modulated signals on the magnetic tape so that each two adjacent blocks contain a same channel component signal and for reproducing the recorded signals from the magnetic tape, two demodulators for demodulating the reproduced signals, and a second switching circuit for exchanging the demodulated signals every nH to obtain the 2-channel component signals. With this arrangement, the recording density is remarkably increased and the cross talk interference hardly occur.

摘要： A video signal recording/reproducing apparatus has, in a recording signal processing section, a first switching circuit for exchanging 2-channel component signals at intervals of nH (n: any integer, H: horizontal scanning period) to obtain two combined signals each containing the 2-channel component signals which appear alternately at periods of nH, and a first delay circuit for delaying one of the two combined signals by nH so that the same kind of signals appear at same timings in the two combined signals. The two combined signals one of which is delayed by nH will not be interfered with each other by crosstalks therebetween which will occur in the subsequent circuits including recording and reproducing heads. A reproduced signal processing section has a second delay circuit for delaying by nH a reproduced combined signal which corresponds to the combined signal which has not been delayed in the recording signal processing section so as to recover the original timing relation between reproduced two combined signals, and a second switching circuit for exchanging the reproduced two combined signals one of which is delayed by nH by the second delay circuit at intervals of nH to obtain the original 2-channel component signals.

摘要： In a system for connecting a video signal recording/reproducing apparatus and a color TV receiver, two component signals--a luminace signal and a carrier chrominance signal--are transmitted separately from each other from the video signal recording/reproducing apparatus to the TV receiver. The video signal recording/reproducing apparatus has first and second output terminals for respectively outputting luminance and carrier chrominance signals obtained from a color video signal reproduced from a recording medium. The color TV receiver has first and second input terminals adapted to be respectively connected to the first and second output terminals of the video signal recording/reproducing apparatus for receiving the luminace and carrier chrominance signals. The color TV receiver may be provided with a switching circuit for selecting a composite video signal received in the conventional manner or the separately received two component signals.

摘要： A signal processing apparatus for changing the frequency characteristics of an input signal, e.g.--a video or audio signal, allows a signal to pass through a transmission circuit in a positive time sequence and then, allows the signal to be transmitted through another transmission circuit having the same transmission characteristics in a reverse time sequence with respect to the positive time sequence. Also, while the transmission circuit is arranged to have a zero-phase characteristic, each segment of a continuous signal is processed throughout a period which is equal to at least two times a duration of an impulse response direction of the transmission circuit. Accordingly, unwanted wave errors appearing at discontinuous regions of the signals are eliminated.

摘要： A PLL circuit for a phase comparator, a low-pass filter (LPF), a voltage-controlled oscillator (VCO) and a frequency divider. A first control circuit is responsive to a discontinuous phase change of a reference signal of the PLL circuit for inhibiting the operation of the phase comparator or disconnecting the LPF from the phase comparator during a predetermined period so that the discontinuous phase change information is not transmitted through the LPF to the VCO. At the same time, a second control circuit resets the frequency divider by a pulse of the reference signal after the discontinuous phase change or applies a voltage corresponding to the discontinuous phase change to the VCO so that the output signal of the frequency divider is locked in phase to the reference signal after the discontinuous phase change. With the cooperation of the first and second control circuits, the PLL circuit quickly recovers its stable state after the discontinuous phase change of the reference signal.
